Lamp with marble base

I think the body of the lamp is porcelain with sculpted roses  

base is attatched to a marble slab, theres a partial silver sticker on the side of the marble that all I can read is the end 'rble'

inside the bottom of the base is written '2748 base made in Italy'

the cord and plug are plastic 

the metal where the bulb socket is says made in the USA dont know if these are originalor not

The shades are a thick paper material with little fabric polka dots and the top and bottom are edged with little pompom balls. I also am not posotive if they are original to the lamp  

I aquired these from my great grandmother when she passed. She lived between 1902 and 1995. 

Thats about all I know about it. Sorry for my lack of any technical terms. I just know they have some age and would like to know if they have anything other than sentimental value.
